Well, since no one else as said it....
HAPPY 30TH ANNIVERSARY TO "THE MUPPET MOVIE"!
June 22, 1979
To answer questions, I never did get to work for Jim again (since he and the Company got so big, and I was so young), but spoke with him briefly on the phone when he was on the set of "The Tonight Show" the night Kermit hosted to promote the film.
Jim and I were corresponding for a few years when he still had time to personally write letters and cards. Lynn Klugman handled all his mail, and when I heard they were shooting the film in Studio City I just called and managed to get her on the phone. She talked to Jim who "would LOVE to meet you", and after he let me do a couple of little blocking and rehearsal things I guess he decided he I was good enough to do the shot, and I got the call a couple of weeks later.
I don know about Richard or Jerry, but Dave came through the crowd of pupeteers as we got comfortable with our characters, and just glanced as us all quickly saying something like "that's fine" and moved on.
I got a lot of local press from doing the film and lots of opportunities after that, including a pilot the Dick Clark created for me for my own late-night talk show. (The host was a puppet character I did.).
BTW-I'm on Facebook if anyone cares! {8>-D
